Definitions
- the invention relates to a two- or multi-component system for the preparation of a dental material according to the preamble of claim 1.
- Polymerizable dental materials of the type mentioned above are known for example from WO 00/78271 Al and find Ver ⁇ application example as filling materials, adhesives,
- Buttstock materials, crown and bridge materials, and temporary crown and bridge materials, and cements are mixed to produce dental materials.
- the components of the system are mixed to a pasty mass and applied. This mass is cured by radical polymerization.
- EP 0 374 824 A1 discloses amine-peroxide systems for polymerization initiation.
- the amines used can be toxic concern, they also often lead to aesthetically unacceptable discoloration of the restoration material. Under certain circumstances, it can also lead to relatively high temperatures during curing, which can damage adjacent tooth material such as the pulp.
- the invention has for its object to provide a system of the type mentioned, which in practice with good Er- is processable and curable and has a good storage stability.
- the invention solves the problem in the aforementioned systems in that the first and / or second component contains at least one peroxide selected from the group consisting of perethers, peracetals and perketals.
- the invention relates to a two- or Mehrkomponentensys ⁇ system , preferably a two-component system.
- the dental material is thus made up of at least two, preferably exactly two components.
- the first component contains at least one free-radically polymerizable resin and a polymerization accelerator which itself does not act as a polymerization initiator and thus does not impair or substantially not impair the storage stability of the first component.
- a polymerization accelerator which itself does not act as a polymerization initiator and thus does not impair or substantially not impair the storage stability of the first component.
- combinations of divalent transition metal ions and halide or pseudohalide ions, in particular chloride ions are used as the polymerization accelerator.
- the second component contains as a polymerization initiator a CH-acidic compound and / or a salt of a CH-acidic compound.
- CH-acidic compounds which have barbituric he reported ⁇ favorable in dentistry. They can be prepared in high yields and purities, are industrially available (Chemische Fabrik Berg GmbH, Mainthalstrasse 3, D-06749 Bitterfeld) and allow the realization of interesting properties by their reaction kinetics.
- the synthesis of the barbituric acid derivatives is known, for example, from E. Fischer and A. Dilthey: "Via c-dialkylbarbituric acids and via the urides of the dialkylacetic acids", Ann. 335 [1904] page 335) and describes the alkaline condensation of derivatives of malon - klarediethylesters alcoholate with N-substituted urea in Natriumal- the sodium salts thus obtained of the ⁇ Barbiturklade derivatives are then converted by the addition of an acid, for example hydrochloric acid, in the barbituric acid derivatives.
- the barbituric acid derivatives In the initiator system based on barbituric acid or derivatives thereof, the barbituric acid derivatives must be stored separately from the polymerizable monomers. This is because that CH-acidic compounds such as the derivatives of the bar ⁇ biturklare even without the participation of Cu (II) - and Clorid- ions by autoxidation by air oxygen hydroperoxides bil ⁇ . These hydroperoxides decompose to form radicals, which initiate the polymerization of the reactive monomers, so that spontaneous polymerization occurs within a short time. This spontaneous polymerization process can be delayed or suppressed by the addition of stabilizers for a short time, but not over a longer period of time, as is desirable in storage-stable systems.
- Part of the second component is therefore in a variant of the invention, a liquid at room temperature or pasty inert matrix, which can not be brought to the polymerization ⁇ merization by the CH-acidic compound.
- Suitable, for example Plasticizers such as polyethylene glycols, which are described in more detail below.
- the second component may also contain radically polymerizable resins.
- the prerequisite for this is that the CH-acidic compound present in the second component is present as a salt.
- a salt-present CH-acidic compound can not yet act as a polymerization initiator in this salt form. For this purpose, it must first be converted, for example by means of an acid, into the corresponding CH-acidic compound itself.
- the second component may ⁇ example, a basic compound containing, stabilizes the salt of the CH-acidic compound, and preferably does not decompose the Peroxidkompo ⁇ component.
- the first component may contain a suitable acid capable of hydrolyzing the salt of CH
- the acid protonates the salt to the free CH-acidic compound, which then acts as a polymerization initiator.

- Suitable drying agents are, for example, zeolites, anhydrous or dehydrated salts such as MgSC ⁇ or CaSC ⁇ -hydhalhydrate, dried silica gel, CaCl 2 and silica gels. Particularly preferred is the use of a desiccant in the component containing the peroxide.
- the components are present as liquids, preferably as (flowable) pastes.
- the preparation is done by suitably mixing the components of the individual components by ge suitable methods such as stirring, kneading, dispersing, rolling, inter alia until homogeneous components are obtained.
- the components of the material are mixed with one another by hand or preferably automatically by means of static or dynamic mixers (for example from Sulzer MixPac®) for hardening.
- static or dynamic mixers for example from Sulzer MixPac®
- other components can be added.
- the components may contain acidic components, such as polymerizable acids or non-polymerizable acids. Weak, medium or even strong acids may be suitable here.
- An optional acid, preferably a medium to strong acid, may then additionally be contained in one or both of the two components.
- the two-component or multi-component system according to the invention can be used for producing a dental material.
- the Herge ⁇ presented dental material is preferably selected from the group consisting of restoratives, adhesives, Stumpf initialmate- rials, crown and bridge materials, temporary crown and bridge materials as well as cements.
- the invention further provides a kit for preparing egg nes Dental material containing an inventive two- or multi-component system ⁇ in suitable containers. It may be suitable storage containers, cartridges for static or dynamic mixers or the like. Component of the kit may be a suitable mixing device such as an already mentioned static or dynamic mixer.
- Embodiments of the invention are hereinafter beschrie ⁇ ben.
- the following commercially available components were used: BisGMA bisphenol A diglycidyl dimethacrylate
- UDMA 7,7, 9-trimethyl-4,13-dioxo-3,14-dioxa-5,12-diazahexadecane-1,16-dimethacrylate (CAS 72869-86-4)
- MEMO-sil silanized with 3.8% by weight of 3-methacryloylpropyltrimethoxysilane
- PEG 400 polyethylene glycol, MW 400
- the paste components of the paste combinations to be measured are filled without air into the chambers of a 10 ml safety double cartridge (Sulzer MixPac) with a mixing ratio of the components of 10: 1.
- a 10 ml safety double cartridge (Sulzer MixPac) with a mixing ratio of the components of 10: 1.
- ISO 4049 are therefrom by automatic ⁇ specific mixture (mixing tip MLX 3.2-12-S 10: 1 green Sulzer Mixpac) prepared 5-6 specimens per material combination, gela ⁇ siege and measured. The mean and standard deviations are each indicated in the result tables.
- the final cure time (EHZ) of the automatically mixed pastes was determined in the rheometer with coaxial cylinders. For this purpose, an approximately constant amount of paste was placed on a lower art ⁇ cylinder material in each case. 30 seconds after the start of mixing, a top metal hollow cylinder, which was permanently tempered to 37 ° C., was pressed into the paste up to a defined distance from the bottom cylinder. The two cylinders were oscillated against each other and the required force was drawn with the help of a pen on ⁇ . The end cure time was the time from which the recorded force remained constant.
- the material is automatically mixed from the safety double cartridge within a few seconds and applied to a mixing block.
- the paste is then at a distance less circulated Se ⁇ customer again and again. If the gelling of the paste mixture has progressed so far that a recognizable elasticity occurs and a homogeneous mixing is no longer possible, the gel time point is reached. Indicated is the time from the end of the automatic mixing process until the gel time.
- the material is added from the safety cartridge with double mixing ⁇ cannula within a few seconds into a cylindrical mold made of stainless steel with a height of 2.5 ⁇ 0,1 mm and a diameter of 25 ⁇ 0.1 mm and allowed to cure.
- the test specimens thus obtained were stored for about 24 h in water at 37 ° C.
- the specimens were removed and the Barcol hardness determined using a Barber-Colman-Impressors. In each case, 5 values are distributed over a test specimen is determined and formed de ⁇ ren mean.
- Production Example 1 (BTBACl Solution)
- the liquid components, the solutions from the preparation examples and, if contained in the recipe, peroxides are weighed first, so that the proportions, as indicated in the tables below, are achieved.
- the resulting mixtures are stirred to clear solution using an overhead stirrer.
- the respective resin mixtures are quantitatively in one
- Second component plasticizer component
- Second component plasticizer component
- Examples 1 and 2 the barbituric acid and perketal of the present invention contain, even after a storage time of 4 weeks at 40 ° C stable and compared with the peroxide ⁇ free system (Ref. 1) have characteristics significantly improved mechanical egg ,
- the diacyl peroxide (BPO, Ref. 3) shows no positive effect on the mechanical properties of the hardened material and moreover completely deactivates upon storage of the uncured pastes.
- Ref. 2 finally shows that the initiator systems for the presence essence of the CH-acidic compound (PBS, barbituric acid) are angewie ⁇ sen because it does not come to hardening otherwise.
- PBS barbituric acid
